So I'm a couple miles into my 6-mile commute to work and I start to feel play in my cranks. Rather than possibly do damage by riding to work, I head back home, pedaling gingerly, hoping an adjustment will do the trick. Turns out it's play in the Phil Wood bb, not the cranks. I remove the nds ring and start to remove the ds ring, but it doesn't seem to want to slide out. Opps, I forgot to remove the plastic bb guide screw, which is protruding enough to prevent the bb housing from coming out.
Now comes the one simple mistake which has far-reaching consequences. For some reason, perhaps because the screw is positioned upside down, I begin turning it the wrong way. I knew I had applied lock tight to the screw, so I wasn't alarmed when it was tough to turn. Finally, I get suspicious when the plastic bb guide cracks and explodes into a few pieces.
Oh well, no big deal. Like any responsible bike owner, I have a few extras. So now I remove the screw and remove the bb unit.
This pic is what I find. Some how, I managed to tap a perfect hole in the shell of the bb unit. I can hear the "plug" of removed material rattling around inside. If the unit is tipped toward the hole, the plug will acually jam in the nds side spindle.
So now I have to email Phil Wood and explain this clusterf@ck, hoping they can remove the bearings, remove the "plug" and reinstall everything for less than the cost of a new unit.
Through all this, I never did figure out how it got loose in the first place.
